MEASUREMENTS AND FIN RAYS OF Euleptorhampkus longi- 



rostrts. 



We have also numerous young examples of a long-finned Hemiram- 

 phid, apparently a Euleptorhamphus and perhaps Euleptorhamphus 

 longirostris, taken from the stomach of a horse mackerel ( Thunnus 

 thynnus) about 7 26' N. ; 100 26' W., in December; and from the 

 stomach of an ocean bonito ( Gymnosarda pelamis) at about 4 

 30' N. ; 87 W., in July. During July these young individuals were 

 extremely abundant between Clipperton and Cocos islands, but we 

 saw no adults. Those collected are about 75 mm. long; depth about 

 7; sides flat and parallel; pectorals 3-J; beak very short, about 9 in 

 body, but perhaps broken in all, entirely gone in many.
